If Everettian interpretation of QM is right we may face another pale blue dot universe scale realization.
- golergka 4y agoCan you please elaborate? I don't understand.
- jahnu 4y agoThey are referring to many worlds interpretations of quantum mechanics that argues that the quantum wave function is as real as anything. As real as say electromagnetic fields. If this is true then the mathematics say that the universe branches or splits at each quantum event. Here’s a very very good explanation of this: https://m.youtube.com/watch?v=nOgalPdfHxM https://m.youtube.com/watch?v=nOgalPdfHxM
- thaw13579 4y agoCurious though, how does this relate to the JWST?
- mmusson 4y agoIt was implied that we would see another Earth. But that is a science fiction trope.
- thaw13579 4y agoRight, I’m not sure whether this refers to finding another earth-like planet with JWST (interesting and plausible though not related to the many-worlds interpretation of quantum), or seeing another version of the Earth with JWST that followed a different path in possible many-worlds quantum outcomes (seemingly impossible!).
- causality0 4y agoTo the best of my knowledge there's no way for branched universes to ever interact with each other again, so why would a layman even care that they exist, let alone be profoundly changed by that fact?
- freshbakedbread 4y agoI don’t know the science of this possibility, but you should check out the short story Anxiety is the Dizziness of Freedom by Ted Chiang. He writes directly about a future where we have a tool to communicate between branches universes.
- _a_a_a_ 4y agoWhy should I check it out? Is it illuminating, or just a good story, or what?
- freshbakedbread 4y agoSorry I didn’t clarify. It is fiction, but I think it describes a plausible reaction of the general public (the layman of the comment I replied to) to this hypothesis if it was discovered to be true. Don’t want to spoil the good part of the story beyond that!
- _a_a_a_ 4y agoOk, and appreciated! Will dig it up, thanks.
- AnIdiotOnTheNet 4y agoLiterally everything written by Ted Chiang is worth reading because he is a hell of a story teller.
- mr_mitm 4y agoThat's science fiction, though. The Everettian Many Worlds Interpretation is just that: An interpretation of a set of equations. And pretty much by definition the worlds cannot interact in any way. Even if there were some obscure way to differentiate between MWI and, say, the Copenhagen interpretation, I wouldn't expect it to become feasible anytime soon. But as far as I know there cannot be any experiments differentiating between the two (or other interpretations), because they're simply different interpretations of the same equations. They predict the same experimental outcomes.
- jeezfrk 4y agoI think retro-causality explains QM better.
- infogulch 4y agoTo connect the dots that sibling comment nicely laid out, if the universe splits at every decoherence event then its total size is incomprehensibly more enormous than the jump to "the observable universe" when we discovered other galaxies.
